luftdichte
Luftdichte refers to the airtightness of a building envelope, meaning the degree to which uncontrolled air leakage is prevented. This is crucial for energy efficiency, occupant comfort, and the durability of the building structure. Uncontrolled air leakage can lead to significant heat loss in winter and heat gain in summer, increasing the demand on heating and cooling systems and thus raising energy costs.
A well-sealed building envelope also contributes to improved indoor air quality by preventing the ingress of
The measurement of luftdichte is typically performed using a blower door test. This test depressurizes or overpressurizes
Achieving good luftdichte involves careful design and construction practices, including the proper installation of air barriers,
